Audiongon Bluebook accuracy


Hello,

I have used the Audiogon bluebook several times, but I am not sure that it is very accurate in some cases. It seems to be more accurate when there is more sales data to draw from nut if there are only a few sales of a particular item, I am somewhat skeptical.

I am looking to buy a used Audio Research REF Phono 3 (not an SE) from a local dealer, and I am not sure what a fair price would be for a unit with just over 300 hours.

I guess that I have two questions that I respectfully ask for assistance for:

Where can I find another bluebook source?

What should I pay for a used ARC REF Phono 3?

Happy Listening!

P.S. Sorry that I typo's Audiogon in my post title.

What I found with the Audiogon bluebook when I subscribed several years ago is that average price is not weighted based on age.

this is true, though they try to keep models and versions updated to some degree

Hifi shark is a good choice for a reasonably clear picture of what items are listed for. 

What I found with the Audiogon bluebook when I subscribed several years ago is that average price is not weighted based on age. IOW, if an item were 2 generations old, the sales from when it was current production was considered the same as current pricing. Agon bluebook average tends to be over inflated. I am not sure if the average pricing method has changed or not for the bluebook.

all info sources are limited by the quality and availability of input data
